OIL Benn-Ea This invention relates to oil burners and more particularly to oil or burner rings for.

such burners.

With burners now in use the burner ring is permanently attached to base of the burner being cast with the burner in one piece thereby preventing the removal of the ring for the cleaning thereof, andv should the ring require repairing it is necessary to replace the entire burner. I

A primary object of this invention is to overcome these disadvantages and provide a burner with a ring constructed to be raised 7 above the fire pot thus effecting a saving of fuel and which is also removable for cleaning and repairs and be connected with the burner by the nipple through which oil is supplied.

In carrying out these objects the invention is susceptible of modification without depart-l the ing from the spirit or sacrificing any of advantages of the claimed lnvention; there being shown in the drawings for illustrative purposes a preferred and practical form in "removable cover member'o'r capl is designed tobe seated. This member '15 isfshaped as which,

Figure '1 represents a side elevation of an oil burner constructed in accordance with this invention,

Figure 2 is a plan view of the burner with the cover member removed,

nipple 5 which projects at its inner end beyond the bottom of the fire box 2 and is designed to receive and support a removable ring 10. This ring is made truncatedcone shape in form and has a central passage 11 opening through the apex thereof, the

lower end of said passage being threaded for and aflixed to the" I burners of this "kind. I this ringprov'ides for the' cle'ansing of these which is so constructed as to and having correspondingly shaped collars surroun'ding' the openings and extending upwardly' into the bowl with seats 8 arranged connection with-the nippl'e'by means of which thel'ring' i's detachab'ly mounted and connected with the bowl 2/ This ring 10 is provided with. a, plurality of annular stepped" 'oi l 'grooves-.,l2 such as are-0rdinan1yused in" The removability of grooves as wella's the replacement of the ring ing to the 'us'e' of the" burner.

It will thus be seen that thepec'u'liar' constrirctionand mounting of the burner ring 10 f'to provide-for its ready removal and applica tion, when desired, constitutes an important "feature of the? invention,

' are box or bowl Wis-provided at dia- "Inetricallyopposite'points with air inlet'open 6 and 7 shown triangular in cross-section around tl1e';upper edge'sfthereofon which a shown in Figures ram 3 of'the drawings l providing a hollow'cas'ing having in its hottorn an opening 16 arranged directly over the apex of the biiir'ner i g 10, and dep'ending 17 the ends of which are designed hollow arms to reston the seats 8 over'the' openings 6 and 7 for a purpose to be described. The hollow member -'forms'an air-supply chamber or cap, the air'being'admitted through the openings 6 and 7 and passes down through the opening 16 in the cap where it mixes and burns with the gas generated by the oil flowing over ring 10. This burned gas passes out around the cap 15 into the furnace and out through the smoke stack.

A solid block-like member 9 is formed at the inner end or corner of opening 7 and has a threaded socket 13 in its lower face to receive a pipe, not shown, for discharging the overflow oil from the burner which enters the pipe through a lateral passage 14. This overflow is provided in case the flame should go out and the oil continue to run in, and the excess oil may be conducted to any desired point.

In the use of this burner the parts being in the position shown in Figures 1 and 3, oil is admitted through the opening 4, nipple 5 and passage 11 and flows down over the grooved face of the ring 10 in a thin film where it contacts with the air admitted through the opening 16 in cap 15. 7

Should the ring 10 become carbonized and require cleaning all that is necessary is to lift off the cap 15 and unscrew the ring 10 from the nipple 5 and, if desired, another burner ring may be substituted and theburner continue to operate while the old ring is being cleaned. The truncated-cone shape of the burner ring raises the oil retaining space thereof above the bottom of the fire pot and thus keeps the ring hotter to facilitate generation of vapor thereby effecting a saving of 7' fuel.

Without further 'description it is thought that the features and advantages of the inven-,

tion will be readilyapparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportions and minor details of construction may be resorted to, Without departing from the spirit of the invention or the scope of the claim.

We claim 7 An oil burner having a fire box with an opening therein, a burner ring removably mounted over said opening, said box having openings on opposite sides of said ring surrounded by upstanding collars, a block-like member formed atone side of one ofsaid openings and provided with a pipe receiving socket having a-laterally extending passage opening into the fire box above the bottom thereof forming an overflow for excess'oil, and a hollow casing-like cap cover mounted over said fire box and having depending hollow arms communicatingwith the openings at opposite sides of the burner-wring and having an opening arranged direc'tlyover the burner ring whereby air is admitted through said arms and discharged above said ring and mixed with the gas generated on the ring, said fire box being open on opposite sides of said cap. a
